Macquarie River a watercourse that is part of the Macquarie–Barwon catchment within the Murray–Darling basin, is one of the main inland rivers in New South Wales, Australia.

The river rises in the central highlands of New South Wales near the town of Oberon and travels generally northwest past the towns of Bathurst, Wellington, Dubbo, Narromine, and Warren to the Macquarie Marshes. The Macquarie Marshes then drain into the Darling River via the lower Barwon River.

Lake Burrendong is a large reservoir with capacity of 1,190,000 megalitres (42,000×10^6 cu ft) located near Wellington which impounds the waters of the Macquarie River and its tributaries the Cudgegong River and the Turon River for flood control and irrigation.[3]

The river was first discovered near Bathurst by European explorer, George Evans in 1812 and named in honour of Lieutenant-Colonel Lachlan Macquarie,[1][2] who served as the last autocratic Governor of the Colony of New South Wales, from 1810 to 1821.

Geography

The Macquarie River, not far from its source, near Bathurst

From its origin the Macquarie River flows for 960 kilometres (600 mi) and drops around 517 metres (1,696 ft) over its length.[4] Lake Burrendong at 346 metres (1,135 ft) is the only dam along the length of the river.

Sources

The Macquarie River starts below the locality of White Rock near Bathurst at an elevation of 671 metres (2,201 ft).[4] It is a combination of three water systems which are Davy's Creek, the overflow from Chifley Dam which fed by the Campbells River, and the Fish River which flows into and out of the Oberon Dam.

Communities and bridge crossings along the river

Location Bridge name Comments/use Image
BathurstRailway bridge, Main Western RailwayThis bridge serves the Main Western and Broken Hill railway lines. The wrought iron lattice girder bridge was constructed in 1876 to the design of John Whitton, the Chief Engineer of the New South Wales Railways, and is listed on the New South Wales Heritage Register.[5] The railway bridges at Wellington and Dubbo (see below) are to the same design.
Evans Bridge, Great Western HwyA road and pedestrian crossing for the Great Western Highway/Sydney Road. The Evans Bridge is Bathurst's main traffic thoroughfare across the Macquarie River, linking the central business district with Kelso, and hence, Sydney.
Denison Bridge Constructed between 1869 and 1870, this bridge replaced a bridge at the same location that was washed away by floods in 1867. It is the second oldest metal truss bridge remaining in New South Wales[6] and now serves pedestrian traffic only.
Gordon Edgell BridgeA low level road and pedestrian bridge, north of George Street, this bridge is often subject to localised flooding.[7][8]
Rankens Bridge, EglintonConstructed circa 1856 to serve road traffic, to a design by Mr George Ranken and funded with his support.[9][10] It was damaged in the floods of 1867,[6] but subsequently restored. It is now subject to a weight restriction.
WellingtonRoad bridge, Mitchell Hwy[11] One span of the previous bridge collapsed in February 1989 due to a truck damaging a truss. A temporary pontoon bridge was installed about 500 metres (1,600 ft) downstream by engineers from the Army's 17th Construction Squadron, and used until the current bridge was completed in 1991.[12]
Temporary pontoon bridge, Mitchell HighwayLight Assault Floating Bridge (LAFB) constructed in 1989 by Sappers from 9 Troop, 17 Construction Squadron at Wellington NSW; Troop Commander Lieutenant Andrew Stanner.

Catchment

The Macquarie system covers an area of more than 74,000 square kilometres (29,000 sq mi). Over 72% of land is flat, with an additional 17% undulating to hilly. The remainder is steep to mountainous, rising progressively to elevations above 900 metres (3,000 ft). To the east the boundary is formed by the Great Dividing Range. This boundary extends from near Oberon in the south to Coolah in the north. A well defined ridge extends north-west from the Great Dividing Range for around 400 kilometres (250 mi), then the boundary turns north.[20]

From Bathurst, near the formation of the river, it passes through the following geographic areas:

Rainfall

Rainfall varies across the catchment of the Macquarie River. Generally the peaks and tablelands receive higher rainfall due to the shadowing effects of the surrounding ranges. The Great Dividing Range area receives between 750 millimetres (30 in) and 900 millimetres (35 in) annual median rainfall. This is distributed relatively uniformly throughout the year. Where breaks in the Dividing Range allow the intrusion of moist easterly air streams inland, annual median rainfall of 750 millimetres (30 in) or more is experienced further westward. Further north-west in the Castlereagh and middle portions of the Macquarie valleys the annual median rainfall is 300 millimetres (12 in) to 400 millimetres (16 in).[20]

Rainfall can vary dramatically over several years. For example, records show a variation from >200% to <50% of the average annual figure. Evaporation varies from less than 1,000 millimetres (39 in) south-east of Bathurst up to more than 2,000 millimetres (79 in) at Bourke.[20]

History

Aboriginal history

The Wiradjuri people are the original inhabitants of the area that includes the Macquarie River catchment.[21] The Wiradjuri knew the river as the Wambool.[22] The noted Wiradjuri warrior Windradyne came from the upper Macquarie River region, and was fatally wounded in a tribal battle alongside the river in 1829.[23] Near Carinda, between the Macquarie River and Marra Creek, the oldest evidence of bread making in the world (approximately 30,000 years old) was found at an ancient lake known as Cuddie Springs.[24]

European history

The upper reaches of the Macquarie River were first sighted by Europeans in 1813 and the river was named in honour of the then Governor of the Colony of New South Wales, Lieutenant-Colonel (later Major-General) Lachlan Macquarie. In 1813 Deputy Surveyor of Lands and explorer, George Evans wrote in his journal:[2]

30 November 1813: I have at length reached the Ridge I so much wished to do after walking about 2 Miles, where I had a prospect to the North for a great distance; A Mist arises from a part I suppose to be a River or a large Lagoon about 20 Miles Off; and on 9 December 1813: I have called the Main Stream "Macquarie River".

Two years later Governor Macquarie inspected the country surrounding Bathurst and the Macquarie River and wrote on 10 June 1815, on his return to Government House in Sydney:[25]

At the distance of seven miles from the bridge over the Campbell River, Bathurst Plains open to the view, presenting a rich tract of campaign country of 11 miles in length, bounded on both sides by gently rising and very beautiful hills, thinly wooded. The Macquarie River, which is constituted by the junction of the Fish and Campbell River, takes a winding course through the plains, which can be easily traced from the high lands adjoining by the particular verdure of the trees on its bank, which are likewise the only trees throughout the extent of the plains. The level and clear surface of these plains gives them at first view very much the appearance of lands in a state of cultivation. It is impossible to behold this grand scene without a feeling of admiration and surprise, whilst the silence and solitude, which reign 'm a space of such extent and beauty as seems designed by nature for the occupancy and comfort of man, create a degree of melancholy in the mind which may be more easily imagined than described.

During 1817 and 1818, explorer John Oxley was commissioned to explore the course of the Lachlan and Macquarie rivers respectively. Writing in his journal, published in 1820, Oxley described the junction of the two rivers:[26]

The river in Wellington Valley had been swelled by the late rains, insomuch that the water below its junction with the Macquarie was quite discoloured. From the fineness of the soil, the rain had made the ground very soft, rendering it difficult for the horses to travel..... Our day's journey lay generally over an open forest country, with rich flats on either side of the river .... The river had many fine reaches, extending in straight lines from one to three miles, and of a corresponding breadth. The rapids, although frequent, offered no material obstruction to the boats. The current in the long reaches was scarcely perceptible .... The river expanded into beautiful reaches, having great depth of water, and from two to three hundred feet broad, literally covered with water-fowl of different kinds: the richest flats bordered the river, apparently more extensive on the south side. The vast body of water which this river must contain in times of flood is confined within exterior banks, and its inundations are thus deprived of mischief..... The trees were of the eucalyptus (apple tree), and on the hills a few of the callitris macrocarpa [Note: Callitr. Vent decad.] were seen.... The main bed of the river was much contracted, but very deep, the waters spreading to the depth of a foot or eighteen inches over the banks, but all running on the same point of bearing. After going about twenty miles, we lost the land and trees: the channel of the river, which lay through reeds, and was from one to three feet deep, ran northerly. This continued for three or four miles farther, when although there had been no previous change in the breadth, depth, and rapidity of the stream for several miles, and I was sanguine in my expectations of soon entering the long sought for Australian sea, it all at once eluded our farther pursuit by spreading on every point from north-west to north-east, among the ocean of reeds which surrounded us, still running with the same rapidity as before. There, was no channel whatever among those reeds, and the depth varied from three to five feet. This astonishing change (for I cannot call it a termination of the river), of course left me no alternative but to endeavour to return to some spot, on which we could effect a landing before dark.... To assert positively that we were on the margin of the lake or sea into which this great body of water is discharged, might reasonably be deemed a conclusion which has nothing but conjecture for its basis; but if an opinion may be permitted to be hazarded from actual appearances, mine is decidedly in favour of our being in the immediate vicinity of an inland sea, or lake, most probably a shoal one, and gradually filling up by immense depositions from the higher lands, left by the waters which flow into it. It is most singular, that the high-lands on this continent seem to be confined to the sea-coast, or not to extend to any great distance from it.

By 1828, explorer Charles Sturt was commissioned to ascertain "the limits of the Colony" by following the Macquarie River "for the express purpose of ascertaining the nature and extent of that basin into which the Macquarie was supposed to fall, and whether any connection existed between it and the streams falling westerly".[27] Navigating the marshes (later named in honour of Lachlan Macquarie), Sturt was the first European to discover the Darling River, named in honour of General Ralph Darling.

Water management

Irrigation

The Macquarie River catchment is a regulated Water Management Area and includes private irrigation as well as several public irrigation schemes[28] located at Narromine - Trangie, Buddah Lakes, Tenandra, Trangie – Nevertire, Nevertire, and Marthaguy.

Flooding

The Macquarie River has a history of flooding. Some significant events are listed below. After major floods, water can flow past the Macquarie Marshes and into the Barwon-Darling river system upstream of Brewarrina.[29]

Recreation

Recreational activities are popular along the length of the river particularly in the communities it passes by.
